At these times (Windows 3.1x was the time for 1MB SVGA cards) we also found video drivers by Diamond and Spea to be rather instable for us. The problems were various, from lock ups in either full screen or windowed DOS boxes, to incompatibilities with a secondary video adapter in the same system (HGC) (for debugging), to strange mouse effects. In our institution when then switched to only use video cards based on Tseng Lab s ET4000 or ET6000 chips, or cards manufactured by ELSA (usually were S3 based at these times), as ELSA is known for extremely high quality of their drivers, reliability, and good service. Probably also because we could ask them directly in case of problems, since their headquarters are located here in Aachen. (BTW. Some trivia: Although Elsa is a rather old-fashioned girl s nick-name for Elisabeth, it actually just means "Elektronische Sachen" here, that is "electronic devices". ;-) Right now, I cannot remember any more, what it was exactly, but many (older) Cirrus VGA chips don t supported some peculiarities of the original VGA. During the K3PLUS development (aka FreeKEYB now) I often had other non-Windows related video problems with Cirrus based VGA designs, that s why I have come to avoid them whereever I can...
